Abstract:

 Bismuth and Lead are commonly used for radiation shielding to mitigate risks such as radiation damage and cancer. However, these materials are costly and impractical for certain applications. This study aims to explore the attenuation properties of various elements and composites using Monte Carlo simulations to develop improved radiation shielding materials. GAMOS software was employed to simulate materials with thicknesses ranging from 0.1 to 2.0 mm and x-ray energies between 10 and 150 keV. Initial simulations focused on validating bismuth and lead by calculating their mass attenuation coefficients, which matched NIST National Institute of Standards and Technology values within a 2 margin of difference. After verification, the study simulated various shielding materials incorporating metals and rare earth elements. Among these, four composites with rare earth elements demonstrating the highest mass attenuation coefficients were selected. These composites exhibited superior absorption in the 5080 keV energy range compared to bismuth and lead.

 Bismut ve Kurşun, radyasyonun neden olduğu zarar ve kanser riskini azaltmak için yaygın olarak kullanılan koruma malzemeleridir. Ancak bu malzemeler, maliyetli ve bazı uygulamalar için pratik değildir. Bu çalışma, Monte Carlo simülasyonları kullanılarak çeşitli element ve bileşiklerin zayıflatma özelliklerini inceleyerek daha iyi radyasyon koruma malzemeleri geliştirmeyi amaçlamaktadır. GAMOS yazılımı, 0.1 ila 2.0 mm arasında değişen kalınlıklara sahip malzemeler ve 10 ila 150 keV enerji aralığındaki x-ışınları için simülasyonlar yapmak üzere kullanılmıştır. İlk simülasyonlar, bismut ve kurşunun kütle zayıflatma katsayılarını hesaplayarak bu malzemeleri doğrulamaya odaklanmış ve elde edilen değerler, NISTin Ulusal Standartlar ve Teknoloji Enstitüsü verileriyle 2lik bir fark içinde uyuşmuştur. Doğrulama sonrası, metaller ve nadir toprak elementleri içeren çeşitli koruyucu malzemeler simüle edilmiştir. Bunlar arasından, en yüksek kütle zayıflatma katsayısına sahip dört nadir toprak elementi katkılı bileşik seçilmiştir. Sonuç olarak, bu bileşiklerin 5080 keV enerji aralığında bismut ve kurşuna kıyasla daha yüksek bir absorpsiyon sağladığı görülmüştür.
